Research has shown that the development of early literacy and math skills in preschool is associated with future school achievement in both mathematics and literacy.  Preschoolers are very enthusiastic about exploring the math and science concepts described below and these positive attitudes can also greatly contribute to their future success in school.
Playing with puzzles, building toys, blocks, and games helps preschoolers practice and build math skills 
Math Activities:
Play with Shapes and Patterns: Use blocks, straws, sticks, and other objects to make shapes and create patterns.
Sorting Races: Ask kids to sort different shapes and colors as fast as they can.
I Spy:  Play “I Spy” with shapes and colors. For example say “I spy a circle,” or “I spy something red.”  I Spy books for this.
